CARL MUEHLEISEN, OF BERLIN, GERTJIANY, ASSIGNR TO MERGENTHALER T CINOTYPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL GOMPOSINGJVIACHINE.

Application filed March 29, 1915.

To all whom t may concern:

Be it known that I, CARL MUEHLEISEN, a citizen of the United States of America, residing at Chausseestrasse 23, Berlin N. Ll, in the Empire of Germany, have invented new and useful Improvements in rlypographical Composing-Machines, of which the following is a specification.

This invention relates to typographical composing machines, especially machines such as those known under the trade mark Linotype, in which matrices, stored in magazines, are released from the latter in order of composition, and, after presentation to a casting mold for the production of casts therefrom, are returned to the said magazines.

The present invention deals particularly with such machines as are provided with a plurality of magazines and a single assembler plate, and in which, as is already known, the magazines are pivotally mounted so as to be adjustable relatively to the assembler' plate, or the assembler plate is thus mounted and adjustable relatively to the magazines, so that, at the will of the operator, matrices can be assembled from any of the magazines, according to the font to be employed. In machines of the just-named arrangement, as heretofore constructed, difficulty has been experienced through the track or path followed by the matrices on leaving the magazines and entering the assembler plate entrance, varying for diiferent magazines brought into use, and the object of the present invention is to provide means for overcoming or minimizing that difliculty, said means comprising a member in pivotal relationship tothe assembler plate entrance, and so arranged and controlled that it will occupy practically the same position relatively to each of the magazines when that magazine is itself in operative relationship to the assembler plate entrance.

The invention will now be described by reference to the accompanying drawings, which represent three different constructional forms of the said invention.

In these drawings: Figure 1 is a vertical sectional view of sufficient of a typographical machine to illustrate the embodiment therein of one of such constructional forms, the machine represented being one provided with two pivotally-mounted magazines of which this figure shows the lower one to be Specication of Letters Patent.

in operative position; Fig. 2 is a view corresponding to the upper part of Fig. l, but with the upper magazine Vin operative position; Fig. 2a is a detail view, and Fig. 3 is a vertical sectional view of'a constructional form of the invention embodiedin a machine having four stationary magazines and a pivoted assembler plate.

Like reference numerals are used for indicating like or corresponding parts throughout the several figures of the drawings.

ln the constructional form according to Figs. l and 2, the two magazines l, 2, are capable of being moved angularly about a pivot so that each of them can be brought into and out of operative relationship to the assembler plate 3; the just-mentioned pivot is not shown in the drawings as it is an arrangement which constitutes no part of the present invention and moreover is already well known in the art.

As before-mentioned, Fig. l represents the lower magazine in operative position, and Fig. 2 the upper magazine, and it will be seen by reference to these figures, that whereas the angle of inclination of the upper magazine l and of the assembler plate entrance l is practically the same when these two organs are in operative relationship as in Fig. 2, the angle of inclination of the lower magazine 2, when the latter is in operative position, as shown in Fig. l, diers appreciably from that of the assembler plate entrance.

ln order to satisfactorily guide the matrices 5 into the assembler plate entrance from whichever of the magazines l, 2, is, at the time, in operation, there is provided a horizontal guide bar or switch 6 extending throughout the length of, and pivoted by a rod 7 to, the said entrance so that that bar virtually constitutes a hinged portion of the back plate of that entrance, capable of being turned from the position in which it is shown in Fig. l to the position in which itis shown in Fig. 2 and vice versa.

rlhe switch 6 has fast to or integral with it, an arm 8 to which is pivoted the upper end of a rod 9 whose lower end is pivotally connected to a slide 10 free to move vertically up and down in a guide slot 11 in the Xed frame 12 of the machine, to which frame the assembler plate 3 is secured in well-known manner. On the front end of the slide is mounted an anti-friction roller 13 constantly held inV contact with an edge cam 14 by a tension spring 15 attached at its respectively opposite ends to the rod 9 and frame 12. The cam 14 is in rigidconnection with a spur wheel 16 capable of rotating about a fixed stud 17 and meshing with a spur pinion 18 fast on a shaft 19 by the rotation of which latter is effected the adjustment of the magazines 1, 2, into and out of operative relationship to the assembler plate entrance 4. The shaft 19 is lrotated by means of a crank handle 20 and a halt rotation of the cam 14 suiiices to move the Y magazines 1, 2, from one terminal position to the other. The means for transmitting motion from thc shaft 19 to the magazines, may be of any suitable construction, that shown in the present instance comprising an upright 'shaft 19EL connected at its lower end by bevel gearing 19b tothe shaft 19, and

connected at its upper end by bevel gearingY 19C to a transverse rock shaft 19d, having fast thereon one or more cams 19c arranged in engagement with the magazines or their supporting frame.- The cam 1'4 is so shaped that, during the movement of the magazines into and out of their respective operative positions, the switch 6 is turned about its j pivot 7 in such manner that when the said operative osition is arrived at the matrixi p a lguiding surface of the switch will have the l whenever an operative change of magazine is made. For attaining this result, the comb plate 22 is secured to a lever or frame 23 capable of rocking about a stationary pivot 24, and having pivoted to it the upper Y end of a link 25 whose lower end is pivoted to the horizontal arm of a bell-crank lever 26. VThis lever is free to turn about apivot 27 fast to the machine frame 12, and has an anti-friction roller 28 pivoted in or to its vertical arm, a tension spring 29 serving to hold the said roller constantly in Contact with a face cam 30. The cam 30 is integral with the edge cam 14, or, in other words, it and the said edge cam are different operative surfaces of one and the same body. By the foregoing arrangement, the act of turning the shaft for effecting an operative change of magazine, automatically eects, simul taneously therewith, the adjustment of the switch 6 and of the escapement reeds 21, so

that when such operative change is completed, these devices will occupy their proper positions relatively to the magazine 1 or 2 and the escapements 31 with which they are respectively to cooperate. Thus when the magazine shifting mechanism is operatedV to change from the lower to the upper magazine, the initial operation of said means brings the low surfacerof the face cam 30 opposite the roller 28 on the pivoted lever tive position, when the raised surface of the cam will rengage the roller and cause the rearwardly into position to engage and actuate the escapement levers as shown in Fig. 2. Y V

1n the constructional form illustrated in Fig. 3, wherein, as an example, four magazines 1, 2,1a and 2a are shown, and wherein, for bringing any one of these magazines into operation, the assembler plate 3 is, as shown in myV co-pending application Serial No. 15,317, swung about a pivotal axis situated at or near its lower end, the arm 8 of the switch 6 is provided with an anti-friction roller 32 which, during such swinging movement of the assembler plate 3, Vtravels over aV stationary cam track 33, which is eccentric to the aforesaid pivotal axis or of such contour as will cause the switch, when in register with any one of the magazines, to assume the angle best suited tobridge the gap between that magazine and the adjacent top edge of' the assembler entrance. In the figure now under review, the assembler plate 3 is shown in full and chain lines inoperative relationship to respectively the maga-V zines 2a and 1. Y
